+
+uIP Applications
+^^^^^^^^^^^^^^^^
+
 This directory contains most of the network applications contained
 under the uIP-1.0 apps directory.  As the uIP apps/README says,
 these applications "are not all heavily tested."  These uIP apps
 include:

-  dhcpc     - Dynamic Host Configuration Protocol (DHCP) client
-  resolv    - uIP DNS resolver
-  smtp      - Simple Mail Transfer Protocol (SMTP) client
-  webclient - HTTP web client
-  webserver - HTTP web server
+  dhcpc     - Dynamic Host Configuration Protocol (DHCP) client.  See
+              apps/include/netutils/dhcpc.h for interface information.
+  resolv    - uIP DNS resolver.  See apps/include/netutils/resolv.h
+              for interface information.
+  smtp      - Simple Mail Transfer Protocol (SMTP) client.  See
+              apps/include/netutils/smtp.h for interface information.
+  webclient - HTTP web client.  See apps/include/netutils/webclient.h
+              for interface information.
+  webserver - HTTP web server.  See apps/include/netutils/httpd.h
+              for interface information.

 You may find additional information on these apps in the uIP forum
 accessible through: http://www.sics.se/~adam/uip/index.php/Main_Page 

+Other Network Applications
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
 Additional applications that were not part of uIP (but which are
 highly influenced by uIP) include:

-  dhcpd     - Dynamic Host Configuration Protocol (DHCP) server
-  tftpc     - TFTP client
+  dhcpd     - Dynamic Host Configuration Protocol (DHCP) server.  See
+              apps/include/netutils/dhcpd.h for interface information.
+  tftpc     - TFTP client.  See apps/include/netutils/tftp.h
+              for interface information.
  telnetd   - TELNET server.  This is the Telnet logic adapted from
              uIP and generalized for use as the front end to any
              shell.  The telnet daemon creates sessions that are
              "wrapped" as character devices and mapped to stdin,
              stdout, and stderr.  Now the telnet session can be
              inherited by spawned tasks.
-  ftpc      - FTP client
+  ftpc      - FTP client.  See apps/include/ftpc.h for interface
+              information.
  thttpd    - This is a port of Jef Poskanzer's THTTPD HTPPD server.
-              See http://acme.com/software/thttpd/.
+              See http://acme.com/software/thttpd/ for general THTTPD
+              information.  See apps/include/netutils/thttpd.h
+              for interface information. Applications using this thttpd
+              will need to provide an appconfig file in the configuration
+              directory with instruction to build applications like:
+
+               CONFIGURED_APPS += uiplib
+               CONFIGURED_APPS += thttpd
+
+Tips for Using Telnetd
+^^^^^^^^^^^^^^^^^^^^^^
+
+Telnetd is set up to be the front end for a shell.  The primary use of
+Telnetd in NuttX is to support the NuttShell (NSH) Telnet front end.  See
+apps/include/netutils/telnetd.h for information about how to incorporate
+Telnetd into your custom applications.
+
+To enable and link the Telnetd daemon, you need to include the following in 
+in your appconfig (apps/.config) file:
+
+  CONFIGURED_APPS += uiplib
+  CONFIGURED_APPS += netutils/telnetd
+
+Also if the Telnet console is enabled, make sure that you have the following
+set in the NuttX configuration file or else the performance will be very bad
+(because there will be only one character per TCP transfer):
+  
+  CONFIG_STDIO_BUFFER_SIZE   Some value >= 64
+  CONFIG_STDIO_LINEBUFFER=y  Since Telnetd is line oriented, line buffering
+                             is optimal.
+
+Tips for Using DHCPC
+^^^^^^^^^^^^^^^^^^^^

 If you use DHCPC/D, then some special configuration network options are
 required.  These include:
